Der 6m Aegean SIX Contest steht an ... also eine (bessere) Bazooka.

Die im 2019 gebaute war einfach in der QRG zu hoch und ich brachte sie einfach nicht auf die ca 50100 kHz (war immer bei 56 Mhz).
Also gibt es eine auf 50100 kHz neu berechnete Bazooka.

ENGLISH VERSION below bc anybody has an idea ???

On 5./6.June 2021 the Aegean SIX contest is held for 24 hrs, and I want to participate as SV8/HB9FIH from LOC KM39gc (Island Lesvos).
Shack is my small sailing ship 29 ft.

I checked days before the Bazooka which I built in 2019.
But the res Frequency is too high for the advised QRG abt 50 100 kHz.
So I decided to make another one.

Choice of cable:
I must take a lightweigth one because I would like them also use on SOTA.
I took the RG58 - 50 Ohm.
The bandwith is not critical, I will work abt 50 100 +/- max 100 kHz.

Dimensions:
I calculated with different Programms the dimensions.
All where different.
I choosed the 1.Variante bc I made also a 20m Bazooka with them and it fitted very well.
But for the 50 100 kHz the calculated length also did not match 100%.
I tried to tune by changing the end of each leg, but the effects where marginal.
My solution - using a tuner.
I am wondering how I am able to tune the Bazooka just on 50 100 kHz for best SWR (looking for 1:1) without Tuner..?
I will try ontime to open the middle of the inner wire and insert a capacitor or a coil - maybe the Nano VNA helps me to find the right way.
Because I work most time in QRP (CW and a bit SSB) I have no power to giveaway...(to heat the tuner eg) .
 
I wrote this in en (sri for the poor english),
hopefully one of the Bazooka specialists read this and give me a solution, idea or some tips.

Btw: the Aegean contest was succesfull for me, made 27 QSO (23 in CW / 3 in SSB) with 5 Watts, worked abt 7 hrs.
Most fare distance was 1900 km to Germany, most active OM's came from Ukraine, Poland and Israel. Also Malta and Cyprus worked.
Not bad for my QTH position on the ship in the marina of Mitiline (with a lot of wires in the neiberhood).
